This publication focuses on age-friendly living environments and a memory-friendly society. These themes affect the whole society, and we can see them in the environment close to us and in our every-day activities. This publication is meant for anyone interested in developing age-friendliness: older people, professionals and students of different fields, developers and teachers. We hope that our publication is useful to actors in age-friendly societies. It would also be great if this publication could spark discussion around age-friendly and memory-friendly living environments in the society at large.
